Advantage for YC Offence

[rubyref]

Lust getting round to watching Heineken games from the weekend as was away touring with a U13 team I help to coach at the weekend.

Perp. vs Toulon. About 34 min mark high tackle by Perp. on Toulon #7. Toulon #7 stays on feet through the 'tackle' and carries on with his run.

Ref blows immediately and YC to offender.

But why no advantage?

Management judgement in context of the match at that moment.

Anticipating flashpoints to follow, had Perp been warned for high tackles already, etc ?
